I understood what you meant, but in handling I include how it behaves on the limit. I don't just mean the limit from driving like a maniac, I mean when the kid on a bike runs out in front or swerving to avoid a kangaroo at highway speeds. An X5 will never be as safe as a 5 series in this regard - it will not stop as quickly, it wont turn as well, and is obviously more likely to roll over.Everything has limits, including cars.
WHen I was talking about X5, I was talking about actual handling, not electronically assisted stuff.
My wife's Tiguan, 2011, one that has stiff, typical VW suspension, is an absolute blast to drive, and I will take that CUV to track against many cars. So, it is possible to make SUVs handle well, the same as it is possible to make cars handle like crap.
What I am talking about when it comes to the current Tiguan in the US is that it is tuned differently, not because of inherent weaknesses of SUV type of vehicle, but because. VW made that choice.
The modern ones present as "normal" (if you ignore the nauseating sideways rock they all do...), and you usually only find out the hard way they have far lower limits to their handling when **** gets real - which is exactly where you really really need good handling and roadholding!
I understood your point re the US spec VW - my point was that softening up the suspension to make soft US bums happy simply unmasks the inherent physics problems involved in making a car very heavy and top heavy.
